The huge, storm-wracked planet Saturn, made of rock, ice and gases is fascinating for its rings, visible from Earth and photographed here by the Cassini space probe. Their variety is suggested by the Cassini photo color-coded for different temperatures. Saturn itself is lifeless, and speculation centers on one of its moons as possibly harboring microbial life--but so far it's just a theory. There's long been speculation about life on other moons of these distant planets, but so far the presence of life has been confirmed on only one celestial body in the solar system--and its photo is below.

I need to give the link to this blog to my son. He would love these photos you've been posting even more than I do.
